It's also a bit frustrating that Kait's arc in this game has no conclusion. We spend a hell of a lot of time in the middle of the story learning about her, only for her to be marginalized in the climax by a minor appearance of her grandmother and the final battle. They wrote this assuming players would play Gears 6, which I think is a tragic misstep given this game has such a great start.
JD and Fahz's arcs aren't quite tied up either, except by JD dying if you save Del.
